    Hi, new here and would be glad of some help please!

    I am trying to produce the following circuit, which I have attached.


    I bought a DPDT relay which has more pins than I need, but could someone please tell me which pins go where for the circuit? The wiring diagram for the relay is below.


    My electronics knowledge is somewhat limited, I am ok with the rest of it but it's just this that has thrown me!

    Thank you in advance :)

    I would suggest the two pins connected directly to "PIN A" and "PIN E" are pins 1 and 16.

    The two connections to the normally open contacts could be 4 and 8

    Hi jwalker.
    Use a meters continuity tester to be sure, but i think power 12 volts to 1 and 16 is the relay coil, and your diagram looks like single pole single throw ( SPST ) and you could use pins 4 and 8 or pins 13 and 9 as the switch contacts, not both for your circuit. Use your meter to be sure on the relays pin out, the coil will give a reading in ohms. Dave. :)

    Hi thanks very much for the replies, looking again at the diagram it's making sense!

    Will be putting this together tomorrow, thanks again for the help
